Scout 9 does not yet support PostgreSQL

[gregmartyn]

It looks like Scout 9 no longer has PostgreSQL support.

Need more information as to why it doesn't.

@taylorotwell linked to pmatseykanets/laravel-scout-postgres#48 in the updated doc. Without that, Scout doesn't work with PostgreSQL. You get: "Driver [pgsql] not supported." when doing a SomeModel::search($query)->get();

[gregmartyn]

If you try using SCOUT_DRIVER=database, it "searches" using ILIKE % search term %, which isn't an indexed full text search. Postgres full text search uses the @@ operator. More on that here: https://www.postgresql.org/docs/current/functions-textsearch.html and the "stored generated column" part of https://www.postgresql.org/docs/current/textsearch-tables.html
